The results indicate that along the axis of dam,the soil mass on slope of foundation pit is unsafe without impervious wall;when setting impervious wall,the hydraulic gradient on slope steps down to the value lower than 0.
结果表明,在坝轴线方向上,无防渗墙时坡面土体在渗透力的作用下是不稳定的,有防渗墙时坡面水力坡降降到0。
2.
The distributions of hydraulic gradient and specific discharge along the transect of the discharge zone were discussed.
根据浅水湖泊与周边含水层的水力关系,首先假设潜水含水层以同厚水平无限延伸,并与湖底以一个较小的坡度相交,然后利用水力学方法对含水层中地下水在湖底表面的水力坡降和渗流量分布进行了研究。
3.
During the process of analysis for the seepage deformation characteristics of Weihe Mide-stream levee foundation ground, the paper, a dopting several methods respectively, makes assessments and deferminations for the soils seepage deformation pattern and critical hydraulic gradient and allowable gradient.
该文在对渭河中游堤基渗透变形特征分析过程中 ,分别采用几种方法对土的渗透变形类型及临界水力坡降或允许坡降进行了判别、确定 ,并根据堤基实际水力坡降与土的允许水力坡降对堤基稳定性进行了评价 ;通过堤基达到稳定渗流所需的时间与本流域实测最大洪水历时的对比 ,对堤基稳定性进行了验证。

水面坡降
1.
Based on the chart of Modaomen underwater topography in 1964, 1977 and 2003, through the numerical simulation by using the of ECOMSED ocean numerical model, the hydrodynamic field of modaomen in the flood season is simulated, and its’ tidal flow, water level descent .
利用磨刀门1964年、1977年、2003年的地形,通过ECOMSED模型模拟了磨刀门海域洪季水动力场,对潮流、水面坡降、潮能通量等特性进行对比,发现整治后磨刀门水动力强度加大,而且流速滩槽分异明显;落潮期间上游水位均大于下游水位,水面坡降落潮比涨潮大一个数量级;水深与流速是决定潮能大小的主要因素,同一位置随着泥沙淤积河床变浅,潮能通量也减小。
6) gradient ratio (GR)
